Rework "arch/x86/boot/Makefile" to allow it to build both file
"cmdline.S" and "reloc.S" without "build32.mk".
These will now use the main rules for "%.o: %.c", and thus generate a
dependency file. (We will not need to track the dependency manually
anymore.)
But for that, we need to override the main CFLAGS to do a 32bit build.
We introduce XEN_TREEWIDE_CFLAGS which can be reused in boot/Makefile,
and avoid the need to reparse Config.mk with a different value for
XEN_TARGET_ARCH. From this new $(XEN_TREEWIDE_CFLAGS), we only need to
change -m64 to have the 32bit flags. Then those are applied only to
"cmdline.o" and "reloc.o".
Specifically apply the rule "%.S: %.bin" to both cmdline.S and reloc.S
to avoid make trying to regenerate other %.S files with it.
There is no change expected to the resulting "cmdline.S" and
"reloc.S", only the *.o file changes as their symbol for FILE goes
from "cmdline.c" to "arch/x86//cmdline.c". (No idea why "boot" is

We are going to make other modifications to the cloc recipe, so this
patch prepare make those modification easier.
We replace the Makefile meta programming by just a shell script which
should be easier to read and is actually faster to execute.
Instead of looking for files in "$(BASEDIR)", we use "." which is give
the same result overall. We also avoid the need for a temporary file
as cloc can read the list of files from stdin.
No change intended to the output of `cloc`.

In a future patch, when building a subdirectory, we will set
"obj=$subdir" rather than change directory.
Before that, we add "$(obj)" and "$(src)" in as many places as
possible where we will need to know which subdirectory is been built.
"$(obj)" is for files been generated during the build, and "$(src)" is
for files present in the source tree.
For now, we set both to "." in Rules.mk and Makefile.clean.
A few places don't tolerate the addition of "./", this is because make
remove the leading "./" in targets and dependencies in rules, so these
will be change later.

This is to avoid arch/$arch/Makefile having to recurse into parents
directories.
This avoid duplication of the logic to build prelink.o between arches.
In order to do that, we cut the $(TARGET) target in the main Makefile in
two, there is a "prepare" phase/target runned before starting to build
"prelink.o" which will prepare "include/" among other things, then all
the $(ALL_OBJS) will be generated in order to build "prelink.o" and
finally $(TARGET) will be generated by calling into "arch/*/" to make
$(TARGET).
Now we don't need to prefix $(ALL_OBJS) with $(BASEDIR) as it is now
only used from the main Makefile. Other changes is to use "$<" instead
of spelling "prelink.o" in the target "$(TARGET)" in both
arch/*/Makefile.
Beside "prelink.o" been at a different location, no other functional
change intended.

Currently, the xen/Makefile is re-parsed several times: once to start
the build process, and several more time with Rules.mk including it.
This makes it difficult to work with a Makefile used for several
purpose, and it actually slow down the build process.
So this patch introduce "build.mk" which Rules.mk will use when
present instead of the "Makefile" of a directory. (Linux's Kbuild
named that file "Kbuild".)
We have a few targets to move to "build.mk" identified by them been
build via "make -f Rules.mk" without changing directory.
As for the main targets like "build", we can have them depends on
there underscore-prefix targets like "_build" without having to use
"Rules.mk" while still retaining the check for unsupported
architecture. (Those main rules are changed to be single-colon as
there should only be a single recipe for them.)
With nearly everything needed to move to "build.mk" moved, there is a
single dependency left from "Rules.mk": the variable $(TARGET), so its
assignement is moved to the main Makefile.

We are going to need the variable XEN_BUILD_EFI earlier.
But a side effect of calculating the value of $(XEN_BUILD_EFI) is to
also to generate "efi/check.o" which is used for further checks.
Thus the whole chain that check for EFI support is moved to
"arch.mk".
Some other changes are made to avoid too much duplication:
- $(efi-check): Used to avoid repeating "efi/check.*". We don't
set it to the path to the source as it would be wrong as soon
as we support out-of-tree build.
- $(LD_PE_check_cmd): As it is called twice, with an updated
$(EFI_LDFLAGS).
$(nr-fixups) is renamed to $(efi-nr-fixups) as the former might be
a bit too generic.
In order to avoid exporting MKRELOC, the variable is added to $(MAKE)
command line. The only modification needed is in target "build", the
modification target "$(TARGET)" will be needed with a following patch
"build: avoid re-executing the main Makefile by introducing build.mk".

rules to generate those targets; there is an additional ".file" symbol

tools/symbols have an heuristic to try to pick up the right ".file".
This patch adds new .c source file which avoid the need to add a
second ".file" symbol and thus avoid the need to deal with those
issues.
Also remove __OBJECT_FILE__ from $(CC) command line as it isn't used
anywhere anymore. And remove the macro "build-intermediate" since the

Running $(MAKE) like that in a $(shell ) while parsing the Makefile
doesn't work reliably. In some case, make will complain with
"jobserver unavailable: using -j1. Add '+' to parent make rule.".
Also, it isn't possible to distinguish between the output produced by
the target "xenversion" and `make`'s own output.
Instead of running make, this patch "improve" `version.sh` to try to
guess the output of `make xenversion`.
In order to have version.sh works in more scenario, it will use
XEN_EXTRAVERSION and XEN_VENDORVERSION from the environment when
present. As for the cases were those two variables are overridden by a
make command line arguments, we export them when invoking version.sh
via a new $(XEN_FULLVERSION) macro.
That should hopefully get us to having ./version.sh returning the same
value that `make xenversion` would.
This fix GitLab CI's build job "debian-unstable-gcc-arm64".
